Unit 2 Test Review

Front

What is the relationship between frequency and energy in electromagnetic waves?

Back

Frequency is directly proportional to energy; as frequency increases, energy increases.

Front

List the visible light spectrum from lowest energy to highest energy.

Back

red, orange, yellow, green, blue, violet

Front

What is the correct electron configuration for Boron?

Back

1s² 2s² 2p¹

Front

What did Rutherford discover about the structure of the atom?

Back

Rutherford discovered that atoms contain positively charged protons in the nucleus.

Front

True or False: The mass number is the total number of protons and neutrons in an atom.

Back

True

Front

Define frequency in the context of electromagnetic waves.

Back

Frequency is the number of cycles of a wave that pass a point in one second, measured in Hertz (Hz).

Front

What is the significance of the visible light spectrum in relation to energy?

Back

The visible light spectrum represents the range of electromagnetic radiation that can be seen by the human eye, with varying energy levels.

Front

Explain the concept of electron configuration.

Back

Electron configuration describes the distribution of electrons in an atom's orbitals, indicating how many electrons occupy each energy level.

Front

What is the role of protons in an atom?

Back

Protons are positively charged particles found in the nucleus of an atom and determine the atomic number and identity of the element.

Front

How do neutrons contribute to the mass number of an atom?

Back

Neutrons are neutral particles in the nucleus that, along with protons, contribute to the total mass number of an atom.
